Definitions
- the present invention belongs to the fields of pharmaceutical chemistry and gastroenterology, and provides a method of treating, or preventing the recurrence of, inflammatory bowel disease, and reducing the risk of cancer in inflammatory bowel disease, making use of a series of phenylpyrazoles and phenylisothiazoles.
- IBD Inflammatory bowel disease
- UC ulcerative colitis
- CD Crohn's disease
- UC ulcerative colitis
- the symptoms of each disease are characterized by periods of relapse and remission over many years.
- the principal symptoms of UC are diarrhea and rectal bleeding. These symptoms may occur in CD of the colon, but when other areas of the bowel are involved, CD tends to cause abdominal pain, weight loss, malaise, fever, and malabsorption as well as diarrhea.
- CD more commonly than UC, strictures, fistulas and abscesses within the abdominal cavity may occur.
- UC and CD Medical treatment of UC and CD is similar and at present unsatisfactory. Active relapses are usually treated with corticosteroids (intravenous, orally or topically) with their attendant side-effects. Sulphasalazine and its derivatives (5-aminosalicylic acid) can be used in active disease and are effective in reducing the incidence of relapse in UC; all have occasionally troublesome side effects. Immunosuppressive agents such as azathioprine and 6-mercaptopurine are used in patients not responding to steroids or sulphasalazine and again have adverse effects. When currently available medical therapy fails, surgical resection of affected bowel is necessary, but this is not curative in CD as disease frequently recurs in residual intestine.
- ROM reactive oxygen metabolites
- ROMs are instrumental in the pathogenesis of both ulcerative colitis and Crohn's disease, and that the severity of the disease is related to the extent of their over-production. Antioxidant therapy or agents preventing or blocking the formation of ROMs can therefore prove beneficial.
- sulphasalazine and its derivatives may work in IBD, at least in part, by scavenging ROMs.
- Yamada et al. Antioxidant Properties of 5-Aminosalicylic Acid: Potential Mechanism for its Antiinflammatory Activity. In Williams, Ed., Trends in IBD Therapy, Lancaster: Klumer Acad. Publ., 73-84 (1990); Ahnfelt-Ronne et al., cited above.
- ADPRT adenosine diphosphate ribosyl transferase
- the present invention provides a method for treating or preventing the recurrence of inflammatory bowel disease comprising administering to a patient in need thereof an effective dose of a compound of the formula ##STR1## wherein X is a sulfur atom, a nitrogen atom, or a methyl-substituted nitrogen atom;
- R is hydrogen, amino, C 1 -C 3 alkylamino, or hydroxy
- R 1 is hydroxy, or OM
- M is a nontoxic cation
- R 2 and R 3 independently represent hydrogen, halo, C 1 -C 3 alkyl, trifluoromethyl, or C 1 -C 3 alkoxy.
- the invention also provides the use of compounds of formula I for treating or preventing the recurrence of inflammatory bowel disease, including preventing colorectal cancer resulting from and in conjunction with IBD, and further provides pharmaceutical formulations which are adapted for that purpose.
- the group X can be a sulfur atom, a nitrogen atom or a methyl-substituted nitrogen atom.
- the isothiazole and pyrazole rings are both aryl, that is, fully unsaturated, the location of the double bonds in those rings depends on the nature of the X group, as will be readily understood by the reader. The various possible configurations of that ring are well explained and exemplified in the three Beck et al. patents.
- the carboxylic acid group on the pyrazole or isothiazole ring may exist as the acid itself, or as a salt, in which the cation of the salt is represented by M.
- Pharmaceutical chemists often prepare such drugs as alkali metal salts, wherein M would be sodium, potassium or lithium.
- M can also be alkaline earth cations such as magnesium or calcium, a nontoxic metal cation such as aluminum or zinc, or an ammonium ion such as piperazinium, butyltrimethylammonium, piperidinium, phenyl-triethylammonium and the like.
- the preferred salt-forming moieties include alkali metals and quaternary ammonium groups. More particularly, sodium, potassium, lithium, and quaternary ammonium groups wherein the nitrogen atom is substituted with four hydrogen, C 1 -C 18 alkyl, phenyl or benzyl moieties are preferred.
- quaternary ammonium groups such as ammonium, tetramethylammonium, diethyl-dimethylammonium, diethyl-dibutylammonium, benzyltrimethylammonium, t-butyl-trimethylammonium, phenyl-triethylammonium, diethyldipropylammonium, s-butyl-trimethylammonium, isobutyltriethylammonium, dimethyl-bis(tetradecyl)ammonium, trimethyl-octadecylammonium, diethyl-decyl-heptadecylammonium and the like are useful and may be chosen for convenience in the circumstances.
- X is a sulfur atom
- X is a nitrogen atom
- X is a methyl-substituted nitrogen atom
- R is hydrogen or amino
- R is amino or alkylamino
- R is hydroxy or hydrogen
- R 1 is hydroxy
- R 1 is OM
- M is a metal ion
- M is an ammonium ion
- R 2 and R 3 independently represent hydrogen, halo or trifluoromethyl
- R 2 is hydrogen and R 3 is trifluoromethyl
- R 2 and R 3 independently represent hydrogen, alkyl or alkoxy.
- chemiluminescence assay makes use of 300 ⁇ M lucigenin to amplify the chemiluminescence. See Simmonds et al., Gastroenterology, cited above.
- the assay method was validated by measuring the chemiluminescence observed in tissues exhibiting various degrees of UC or CD against the chemiluminescence observed in normal tissues. In the normal tissues, the median chemoluminescence measurement was about 8,000 photons/minute/mg wet weight. The median chemiluminescence measurements in tissues from patients with active, severe IBD, increased to as much as about 90,000 on the same scale.
- the effect of the compounds of the present invention was demonstrated by adding a 10 -6 molar concentration of 3-(3-trifluoromethylphenyl)-4-aminoisothiazole-5-carboxylic acid to the buffer in which samples of tissue from UC patients was maintained. It was observed that the addition of the compound inhibited the production of chemiluminescence by from 8% to 70%, with a median inhibition of about 25%, indicating a corresponding reduction in the presence or activity, or both of the reactive oxygen metabolites in the tissue.
- the treatment methods of the present invention are useful and beneficial to all patients suffering from inflammatory bowel disease, including patients with ulcerative colitis and those suffering from Crohn's disease. Both patients who are suffering from an active outbreak of IBD and those who have suffered from active IBD, but are presently in a state of remission, are benefited by the present treatment methods
- the present method includes both therapeutic methods, for the treatment of actively suffering patients, and prophylactic methods, for the prevention of the relapse of patients who are at risk of IBD in any of its forms, but who are presently in a state of remission.
- the general routes of administration by which the compounds are effective, and some information about the formulations of them, are taught in the Beck et al. patents, cited above.
- oral administration of the drug is usually preferable, because of the convenience and economy of such administration.
- the compounds may be formulated for oral administration in the usual pharmaceutical forms, such as tablets, capsules, suspensions, solutions and the like.
- the compounds may also be administered intravenously, intramuscularly or even transdermally, if it is particularly convenient to do so, for example, for patients who are so ill that they cannot take drugs orally.
- the compounds may be administered topically, as in the forms of suppositories or enemas, in order to place the drug in immediate contact with the affected tissues.
- compositions for IBD are quite different, and have not previously been disclosed.
- Such compositions are adapted to be administered rectally.
- such formulations are in the liquid form administered as enemas and in the solid form administered as suppositories. Both formulation types are old in the pharmaceutical art and the formulation of the present compounds in such forms presents no unusual difficulties.
- Suppositories in general, are usually prepared from low-melting solid materials, which are administered in the solid form and melt in the rectum, to release the drug which is dispersed in the solid matrix.
- the solids from which suppositories were made were oily or waxy materials, such as cocoa butter and the like.
- Bland petroleum and vegetable waxes have also been used, as have mixtures of vegetable oils thickened with such waxes.
- gelling agents in modern chemistry enables such formulations to be prepared in aqueous-based materials, avoiding the administration of oily and waxy materials, which, of course, are quite foreign to the body.
- Such an aqueous-based suppository can be prepared by dissolving or suspending the drug in water, preferably made isotonic by addition of appropriate inorganic salts, and thickening the mixture by the addition of a gelling agent such as a carboxycellulose, for example, until it has become a soft solid at room temperature but will liquify at the temperature of the body.
- a gelling agent such as a carboxycellulose
- the drug When the drug is to be administered as an enema, it need only be dissolved or dispersed in a small volume, such as 100 ml or less, of an aqueous mixture. It is preferable to make the mixture isotonic, to avoid any upset in the water balance of the affected tissues.
- the vehicle for an enema may be no more complicated than physiological buffered saline. It may be convenient to prepare an enema mixture as a solid, comprising a dose of the drug with appropriate quantities of the buffering salts, to be reconstituted with deionized water at the time of use. Alternatively, if an easily water-soluble salt of the drug is chosen, the appropriate dose of the drug may simply be dissolved in physiological buffered saline and administered in that form.
- the dose of drug to be administered in the practice of the present methods of treatment must be chosen by the attending physician, taking into account the severity of the patient's IBD, the extent of involvement of tissues, and the potency of the specific drug which is chosen. In general, it will be necessary to administer a larger dose if the administration is systemic, such as oral or parenteral, then if a topical administration directly to the affected tissue is chosen.
- An appropriate range of doses is from about 1 to 100 mg/kg., particularly for systemic administration. When topical administration is used, a more appropriate range of doses is from about 0.2 to about 40 mg/kg. A more preferred range of doses, however, is from about 2 to about 50 mg/kg, and a still more preferred dosage range is from about 5 to about 35 mg/kg.
- Disperse the drug in the water for use as an enema mixture Disperse the drug in the water for use as an enema mixture.
- Cocoa butter 3 g
- ammonium salt 500 mg
- ammonium salt 100 mg
- Alginate gel 2 g
